Automobile terminal welding method

Lap and form 

At present, there are two main consumption processes of automotive terminal welding: crimping and ultrasonic welding: Lap is the application of terminals to press multiple strands of wire together to form a joint; Ultrasonic welding is the use of ultrasonic vibration produced by the physical effect of the wire separate. Ultrasonic application in automotive wire harness welding consumption, earlier than Europe and the United States began to prevail, mainly due to the development of foreign ultrasonic metal welding technology. Comparison of two welding technologies:

(1) Lap joint

Advantages: fast consumption speed; The equipment is simple.

Defects: Metal stamping has the risk of rebound; There are risks of oxidation and rust under harsh conditions, all of which can lead to poor contact.

(2) Forming

Advantages: Strong electrical connection characteristics (zero resistance); Insensitivity to the risk of oxidation and rust under harsh conditions.

Defects: Expensive equipment; Cost parts are also more expensive.
